Chicago, United States - November 10, 2025 Chicago's Gold Coast – Video filmed by Nick Liveris captures a rare meteorological event known as thundersnow, with lightning and thunder striking during a snowstorm around 12:23 a.m. on November 10, 2025. The footage was recorded in the Gold Coast area and shows snow sweeping through the streets while flashes of lightning punctuate the storm. This episode is tied to a broader winter system impacting the Chicago area. Heavy lake-effect snow is expected to trigger dangerous travel and whiteout conditions near Lake Michigan, according to a FOX 32 Chicago report from November 9, 2025. Forecasters highlighted snowfall rates that could reach up to 3 inches per hour. Wind gusts topping 30 mph are compounding the hazardous setup depicted in the video. Thundersnow is uncommon. It can form during typical snowstorms when strong vertical mixing creates conditions favorable for lightning and thunder, as explained in a Wikipedia entry updated on November 5, 2025. Warnings for parts of Chicago call for 3 to 6 inches of accumulation in some areas. Totals could be higher depending on how the lake-effect band develops.
